BACKGROUND OF THE INVENTION 1. Field of Invention The present invention relates to a new and useful improvement in cigarettes and the like, and more particularly to ignition tips of self-lighting cigarettes.

2. Description of the Prior Art The main detriment found in most structures of this type is that once the lighting means is ignited, the flame and ember would fade out in no time while the smoker of this type of cigarette is instinctively allowing a moment to get it lit. In such cases as this, the smoker must be very quick to draw on the cigarette as soon as the lighting means is ignited, causing the unpleasant and injurious sulphur fumes to be drawn into the mouth of the smoker. Attempts have heretofore been madeunsuccessfully in perfecting self-lighting cigarettes but, to the best of my knowledge, no one has ever developed a device having the specific combination and arrangement of parts yielding desirable results of that embodied in the present invention.

SUMMARY OF THE INVENTION My device includes a hollow paper cylinder open at both ends. A burning layer is applied over the outer surface of the cylinder. An ignition layer is applied over the burning layer. A paper strip is wrapped around and overlies both one end of the cylinder and one end of the cigarette to secure same together.

When the ignition layer is rubbed against a suitable material such as a layer of red phosphorous secured to an exposed surface of a pack of cigarettes, the ignition layer ignites the burning layer which in turn ignites the cylinder and the adjacent cigarette end. By virtue of the tubular structure of the cylinder, the smoke and fumes of ignition are conducted away from the cigarette rather than through the body thereof, thus increasing smoking pleasure.

It is a well known fact that many past attempts to prepare coal-forming material for the purpose of preparing lighting elements for self-lighting cigarettes relied mainly on paper or composite paper. Paper, no matter how much inflammable chemicals it is adapted to contain therein, provides only a frail coal ember so weak that a cigarette can hardly be lit by it, notwithstanding the unpleasant fumes it emits.

Other coal-forming materials include wood flour, sawdust, textile, weed, etc. Those coal-forming materials are actually not coals and they do not provide, whether treated or untreated chemically, a lasting ember sufficient to light a cigarette, notwithstanding the stinging fumes and gases emitted by them upon their turning to coal, these fumes often being injurious and unpleasant to the smoker.

Through tests and experiments, I found that charred wood or weed, and preferably charcoal in powder form, when mixed with a known nitro-cellulose cotton solution, makes a perfect combustible material for this specific purpose.

Charred combustion materials are lit more readily and have less, if any, objectionable combustion fumes because most, or at least more than half, of the combustion gases and fumes embodied therein are emitted while being charred; furthermore, they have the remarkable quality of retaining coal embers for a longer time, which is the most indispensable and important factor required in the specific purpose of self-lighting cigarettes.

An ignition tip of my invention made in combination with charcoal powder, when ignited, readily flames and retains coal embers for approximately 2 minutes, a time which is deemed long enough to light a cigarette.

Attempts made heretofore in preparing light retaining material for self-lighting cigarettes, so far as I have learned, have been unsuccessful in :solving the problem to which the present invention is directed nor has charcoal or any other charred material ever been used in forming the igniting tip for this type of cigarette.

Advantageous objects may be accomplished by the present invention which embodies among its features a cigarette, a hollow cylindrical tip or ignition tip open at both ends of the same size in diameter as the cigarette, comprising an inner orbase layer of a thin wrapping of cigarette paper, a middle or coal layer of charcoal powder, an outer or ignition layer of safety match tip, a paper strip to secure the ignition tip to the cigarette and a match striking surface provided on a pack of cigarettes.

The primary object of the invention is to provide means capable of being embodied with a cigarette and containing the elements necessary to light same without a match, a lighter or any other outside device.

It is another object to securethe proper and sure lighting of a cigarette by providing at the tip of same, adjacent the tobacco filler, a burningelement of charcoal powder, proven to be the best material available for prolonging and increasing the amount of flame sufficient to properly light the cigarette.

A further object of the invention is to provide a self lighting cigarette which does not need to be drawn upon immediately afterbeing ignited.

FIG. 1 is a perspective view of a first embodiment of the novel tip member of the invention as secured'to a cigarette;

FIG. 2 is a perspective view of a cigarette pack em ployed in the invention;

FIG. 3 is a cut away view of the first embodiment of the novel tip member of the invention per se;

FIG. 4 is a perspective view illustrating the manner in which the novel tip member of the first embodiment of the present invention is ignited;

FIG. 5 is a perspective view of a second embodiment of the novel tip member of the invention as secured to a cigarette;

FIG. 6 is a cut away view of the second embodiment of the novel tip member of the invention per se; and

FIG. 7 is a perspective view illustrating the manner in which the novel tip member of the second embodiment of the present invention is ignited.

Referring now to the drawings in detail, numeral 24 designates a cigarette having a filter 26 secured to one end thereof. Being secured to the other end of cigarette 24 by a paper strip 22 in the manner of a filter to a cigarette is a hollow cylindrical tip, or striking tip, open at both ends and having the same diameter as the cigarette 24, comprising three layers, that is, a base layer 16, a burning layer 18, and an ignition layer 20 or 20.

Of the cylindrical tip, the base layer 16 comprises ordinary cigarette wrapping paper treated with a solution of about 20 percent nitro-cellulose cotton to retain, when dried, a stiffness sufficient to be a base and, also to retain moisture-repellant and quick combustion characteristics. The burning layer 18 comprises charred combustion material, preferably charcoal powder of 150 screen treated with a solution of about 20 percent nitro-cellulose cotton to be in the form of a paste so as to maintain, when applied on base layer 16 and dried, characteristics of stiffness, anti-moisture, quick combustion and to retain lasting coal embers after being ignited. The ignition layer 20 or 20 comprises readily ignitable elements and is formed of a compound such as that used in the well known safety match and which is ignitable merely by friction. This ignitable element is also treated with nitro-cellulose cotton solution so as to retain, when applied on layer 18 and dried, the like characteristics of stiffness, antimoisture and quick combustion.

Referring to FIG. 3, the burning layer 18, in the form of a paste obtained from the above preparation, is ap plied thoroughly over the outer surface of the base layer 16, already stiffened by the preceding treatment of nitro-cellulose cotton solution. And in turn, the ignition layer 20 or 20' in the form of a paste is applied over the dried outer surface of the burning layer 18, as in FIG. 3, or over the circular tip portion of said cylindrical body comprising said cylindrical base layer 16 and said burning layer 18, as in FIG. 6.

Paper strip 22 is then wrapped around and overlies both one end of the cylindrical striking tip 16, 18, 20 and one end of the cigarette 24 to secure same together.

A striking surface 14 of phosphorus is provided on the exposed surface of the side 12 of a cigarette pack 10.

As is apparent from the foregoing, with the inner 16, the burning l8 and the ignition layer 20 or 20' treated, respectively, with the nitro-cellulose cotton solution, the ignition tip of the present invention retains a sufficient hardness to endure the striking force of the user of the cigarette, along with a resistance against possible moisture, while the burning layer 18 of charred combustion material ensures lasting coal embers to properly light a cigarette and less, if any, objectionable combustion fumes to be inhaled by the smoker thereof.

To light the cigarette 24, one merely rubs the ignition tip l6, 18, (20') against the striking surface 14 provided on the side 12 of the cigarette pack 10 in the same manner as in a safety match, as shown in FIGS. 4 or 7. With the present arrangement, the rubbing action causes the striking tip member 16, 18, 20 (20') to burst into flame, thereby, igniting the end of the cigarette 24. The ignition layer 20 or 20', upon being ignited, is quickly consumed, emitting combustion gases and fumes radially and outwardly into the air, while the burning layer 18 of charcoal, upon being ignited by the ignition layer 20 or 20-, gives off combustion gases and odors both outwardly into the air and inwardly into the hollow of the cylindrical ignition tip where the outer air is also present. The charcoal in the form of lasting embers lights the filler of the cigarette 24; therefore the objectionable gases and fumes can hardly permeate the tobacco filler to be inhaled by the smoker.

It will be evident that the present arrangement is very reliable with respect to the manner in which it prevents inhalation of unpleasant gases and fumes, it repels moisture and, most important, ensures a lasting ember by virtue of the charcoal.

From the above description it will be apparent that various modifications could be devised without departing from the inventive concepts herein disclosed.
